Most notable DC character from each year.

[Aahz]

1940, 1941, 1959, 1980 and 2006 being the best examples of that imo.

1940: The Joker, Catwoman, Robin, Hawkgirl, Hawkman
1941: Wonder Woman, Aquaman, Green Arrow
1959: Green Lantern (Hal), Supergirl, Wally West
1980: Cyborg, Raven, Starfire, Deathstroke
2006: Blue Beele (Jaime), Batwoman, Miss Martian, Atom (Ryan)

Imo 2006 should go to Damian Wayne.

Imo 2006 should go to Damian Wayne.

His original debut is 1987. Though his first appearance as Robin is 2006. Still wouldn’t list him as 2006 most notable character...

His original debut is 1987.

Not Really, mean this kid has been the basis for several characters before Damian and that was an else world, but the version of Damian we have now in the comics was imo created in 2006.
Btw. listing Jason Todd as created in 1983 has a similar problem, since the version we have now is a completely different character.

Yeah, actually pondered the idea of including him under 1987, but then decided that would be too much of a contested disconnect, so I changed my mind and included him under 2006 instead.
